' 3Claims. (01.211-114) I This invention relates to new and usefulimprovements in a collapsible shelf and bookcase.

The invention has for an objectthe construction of a device as mentionedwhich is charac- -terized by a plurality of superimposed shelves,

an-dropes associated with the shelves in a particular manner forholdingthem in relatively fixed postions.

More specifically, the invention contemplates passing theropes throughopenings in the shelves and providing. a means for fixedly connectingthe ropes with the shelves.

Still further, in one form of the invention, it is proposed to windtheropes around portions of the shelves in a specific manner, and it isproposed to mount clips on the shelves engaging over portions of theropes to secure these parts fixedly together.

In another form of the invention it is pro posed that the ropes bepassed through tubes Q mounted on the shelves, and to provide projectingportions from the tubes to clip and hold I the ropes.

For further comprehension of the invention. and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawing forming a Ina- I terial part of thisdisclosure;

Fig. l is a perspective view of a collapsible shelf and bookcaseconstructed according to this invention.

I on the line s-a of Fig. 7.

Fig. 9 is a perspective View of the rope holding tubes illustrated inFig. '7.

Fig. 10 is a horizontal sectional view, taken on I the line Ill-40 ofFig. 9.

The collapsible shelf and bookcase, according to this invention,includes a plurality of superimof the top shelf, up through the centernotch I9,

posed shelves 10, II and I2. Ropes I3 and I4 pass through openings inthese shelves and are associated with holding means for fixedlyconnectingthe ropesto the shelves. The upperends ofthe ropes I3 and Mareconnected with rings I5 provided with hooks I6 by which the bookcase maybe supported on an overhead bar or othor support,

Each of the shelves is formed with notches I8 at one side of the frontand rear edge thereof, and a central notch 20 at the center of the sideedge. Each of these shelves is formed with additional notches 20 at thefront and rear edges near the other side thereof, and a central notch 2|at the center of the side edgebetween the notches 20. I. The rope I3 isWound around portions of the shelves between the notches I8, while therope I4 is wound around portions of the shelves between the notches 2D.The winding is identical for each of the ropes. This winding maybeunderstood by examining Fig. 6.

Starting at one end of the rope I3 adjacent the hook I6 the rope extendsdown to the notch l8 in the. top shelf I0, then around the bottom faceacross the top face and down through the notch I8, and further down tothe next shelf II. At this next shelf the rope continues through one ofthe notches I8 around the bottom of the shelf, up through the centralnotch I9, across the top of the shelf and down through the same notchI8. I

The rope then continues downwards to the third shelf I2, and here itextends down through the notch I8, around to the center notch I9, upacross the top face of the shelf, down through the same notch I8 acrossthe entire depth ofthe bottom shelf I2 along the bottom thereof and upthrough the notch I8 at the rear side of the shelf I2. The ropethencontinues around and around I opening 26 for a bolt. The clips 25 areused in pairs (see Fig. 4) one upon the top face of the shelf and theother upon the bottom face. A bolt 2'! is engaged through the openings26. The clips are arranged to extend over the central notches I 9. Theends of the clips engage over portions of the rope immediately adjacentthe notches I9. When the bolts 21 are drawn tight the slips willsecurely hold portions of the rope.

In Figs. 7 and 8 a modified form of'the invention has been disclosedwhich distinguished from the prior form in the mounting and arrangementof the ropes. According to this form there is a plurality ofsuperimposed shelves, 28, 29 and 30. Tubes 3| are mounted through thecorners of these shelves from the top to the bottom. These tubes 3| areformed with projecting flange portions 3W belowthe shelves for fixedlymounting the tubes thereon. Ropes33 pass through the tubes 3!. tubes 3|and engage and hold the ropes 33. The upper ends of the ropes 33 areconnected with hooks 34 which may be used to suspend the article.

While I have illustrated and described the pre-' ferred embodiments ofmy invention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined inthe appended claims.

Portions 3| are crimped in the Having thus described my invention, whatI claim as new, and desire to secure by United States Letters Patent is:

1. A collapsible bookrack or the like comprising a plurality ofsuper-imposed shelves adapted to be supported in spaced relation to eachother, the sides of each of said shelves being divided into front andrear portions by a notch extending inwardly from each side edge thereof,.a supporting rope at each end of said rack, said ropes being wound,successively, around said front portions and, successively, around saidrear portions, and clamping means at each of said notches for holdingsaid ropes in non-slip relationship withsaid shelves.

2. A collapsible bookrack or the like as claimed in claim 1, each ofsaid clamping means includi-ng an elementengaging the shelf adjacentsaid I notch, and the portion of the rope wound around the front andrear portions of the shelf.

3. A collapsible bookrack or the like as claimed in claim 1, each ofsaid clamping means including upper and lower jaws, and a threaded boltengaged through said jaws and disposed in said notch. I
